Rev. Al Sharpton served as the officiating pastor as new parents Nick Cannon and Mariah Carey renewed their wedding vows in a Los Angeles hospital room over the weekend. The songbird, 41, and her much younger hubby celebrated their wedding anniversary with the arrival of fraternal twins on Saturday.

On her three-year anniversary with Cannon, Carey gave birth to a baby girl weighing 5 pounds, 3 ounces, followed by a baby boy, who weighed 5 pounds, 6 ounces. The family listened to Carey’s “We Belong Together” after the babies were born, Carey’s representative, Cindi Berger told PEOPLE.

“Thank you to @THEREVAL who came all the way to the hospital to renew me and my wife’s vows and pray with our children. Yep we just had a wedding in the hospital!” Nick, 30, Tweeted following the ceremony.

Rev. Al followed up with: “I am just leaving Mariah Carey and Nick Cannon. She had twins yesterday on their 3 rd anniversary. I had prayer with them and the babies. I also conducted the renewal of their vows and the blessing of the newborn twins. Mariah looks GREAT, and the babies are beautiful. I am so moved by the sincere spiritual commitment of Mariah and Nick. They have not let success separate them from GOD. I am so proud.”

Mimi’s a mama! Mariah Carey and Nick Cannon celebrated their fourth wedding anniversary by becoming parents to a baby girl and boy on Saturday afternoon.

The girl, the first-born, weighed 5 pounds, 3 ounces and was 18 inches long. Her barely younger brother was 3 ounces heavier and an inch longer. The Cannon-Careys fittingly played Mariah’s hit song “We Belong Together” shortly after their twins were born.

“I’m in the happiest place I’ve ever been in my life,” Nick Tweeted on Sunday. “I never had more amazing things happening. I am humbled by God’s Favor!”

The Grammy winner was calm and relaxed as Cannon, 30, drove her to the hospital in their Rolls-Royce Phantom, but that he was nervous and frantic, even going to the wrong department of the hospital, Carey’s longtime rep Cindi Berger told The Associated Press over the weekend.

“Nick was very nervous and Mariah was completely calm. Mariah thought it was another soft labor and Nick was driving her to the hospital and she very calm and the music was blasting. When they walked into the hospital, [Nick] was going the wrong way and the nurse redirected them to go the maternity ward, and I said to her, ‘that’s right out of I Love Lucy,’ and she laughed.”

Nick and Mariah went through a miscarriage early in their marriage before the songbird, 41, became pregnant again last year. They announced that she was pregnant with twins after informing President Obama and his wife Michelle at a holiday party in Washington in December.

The new parents are still working on names for their new arrivals.

Mariah Carey has stripped off for the cover of the new issue of Life & Style Magazine (on newsstands Friday), revealing her massive baby bump just weeks before she’s due to deliver fraternal twins with husband Nick Cannon.

“I was feeling very vulnerable about taking pictures at all right now, but then I didn’t want to miss this opportunity to document this once-in-a-lifetime experience. My ultimate goal was to share this incredibly personal moment with my true fans,” the expectant mum gushed.

Mariah is one in a long line of famous celebrity bumps to get exposed on the cover of fashion mags. Actress Demi Moore famously posed nude for Vanity Fair in 1991. Britney Spears did it too. Christina Aguilera stripped off for Marie Claire’s Jan. 2008 issue, and ’90s supermodel Claudia Schiffer got naked for German Vogue just last year. Dad-to-be Nick, on the other hand, is already rethinking his decision to strip off. The couple posed together nude in a series of photos peppered throughout the mag, which they plan to put up on the walls of their home.

“My children are going to have to see these pictures. It’s a little weird. It’s a little nasty – I mean, have you ever seen your parents naked? When they get older and their friends come over, they will see the pictures and say, ‘Your daddy’s butt naked.’”

Mother-to-be Mariah Carey will release her sophomore holiday album, Merry Christmas II You, on Tuesday, Nov. 2.

Take a peek at the compilation video released in support of the album’s first single, “Oh Santa.”

“Yes, we are pregnant, this is true!”a beaming Mariah confirmed. “It’s been a long journey. It’s been tough because I’ve been trying to hold on to a shred of privacy.”

The baby is due next spring.

Nick Cannon and Mariah Carey are four months pregnant with their first child, if a number of new reports are to be believed.

RadarOnline.com claims that the singer and her hubby Nick Cannon are expecting their first baby together — after years of fertility treatments — although neither has confirmed the rumor. The couple have been sharing their happy news with close friends only and they wish to keep the matter private.

In addition, Carey’s recent wardrobe choices have done nothing but fuel the rumour mill that the singer is pregnant. This week, Britain’s Daily Mail reported that the brown maxi dress Carey was spotted in last week when she stepped out for lunch at a steak house in Brazil is from the maternity store Pea In The Pod.

The 41-year-old singer is said to be “very excited” about expecting twins with husband Nick Cannon – who she married in May 2008 – but is trying to keep the news quiet.

The Enquirer reports the “Hero” hitmaker is expecting a double bundle of joy.

“Mariah is gushing that she’s going to have twins. Mariah and Nick both want a big family.”

Carey recently dropped out Tyler Perry’s forthcoming film, For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf– citing medical reasons — which fueled rumors of a pregnancy.

A spokesperson for the star refused to confirm or deny the news. “I am not at liberty to discuss Mariah’s personal life at this time.”

The renewal ceremony has become sort of a tradition for the diva and her DJ/rapper/TV producer beau — who wed on April 30, 2008. The couple now renew their wedding vows on each anniversary.

Take a look at the diamond ring pop Nick gave Mariah to mark the occasion.

According to Mariah’s management, the album will not be put out but they are working on releasing some singles that would have prepared on the set: “It won’t go to waste, we were assured.”
